Alternatively, use a tape measure to find the length of each wiper from one end of the blade to the other. Don’t have your owner’s manual or a tape measure? No worries! Most automotive stores have a catalog or electronic system listing which wiper blades are compatible with your vehicle’s make and model.
Lay a towel on your windshield where the blade normally sits. That way, if you bump the wiper arm and it falls back down, it won’t damage or crack the glass.
Some wiper blades don’t have clips and simply snap right into the hook on the arm.
Old wiper blades might feel a little stuck when you try to pull them by hand. Lightly tap on the top end of the blade with a hammer to loosen it up.
After you finish installing your first wiper, change the other blade as well. Chances are if one of your wiper blades needed replacing, then your other one will probably start going bad soon too. [6] X Research source If you have a rear wiper blade, don’t forget to change it too.
When in doubt, check your vehicle’s manual or check wiper size compatibility at an automotive store. Your owner’s manual will list the type of wiper you need, but you can tell if your blades are clip-on if they have a button or clip on the top side of the arm.
Wiper arms are spring-loaded and could snap down against your windshield if you bump it. Place a towel on the glass just in case so it stays protected from damage.
Replace both of your wiper blades at the same time so they don’t wear out unevenly. [11] X Research source
The correct sizes for your wiper blades are also listed in the owner’s manual. You may also check auto parts stores to see if they have a catalog of which wiper blades are compatible with the make and model of your vehicle. You can tell if wipers are pin-mounts since they’ll attach to the sides of the blades rather than through the top.
Lay a towel down on your windshield below your wiper blades. That way, if they fall down, they won’t crack or damage the glass.
If your pin-mount blade doesn’t have a latch, rotate your wiper around the pin until the rubber points away from your windshield. Then, your wiper blade will simply slide off the pin. [15] X Research source
Change the wiper blade on the passenger side at the same time. [17] X Research source
You may be able to stop your blades from squeaking by cleaning them with a little vinegar or rubbing alcohol.
Using your windshield wipers when they’re damaged could leave permanent scratches in the glass.
You may be safe leaving wipers for up to 1 year as long as they don’t show signs of damage.
